摘要
本文用卢瑟福背散射和光吸收技术研究了高剂量Ag离子注入SiO_2玻璃以及退火后的状况.吸收光谱测量表明,注入的Ag离子聚集形成了胶态粒子,其等离子共振峰的极大值在400nm处.运用米(Mie)理论和德拜(Doyle)方法,根据测得的等离子共振峰的光宽度,估算出Ag胶态粒子的半径约为18(?).
High dose Ag+ implanted SiO2 glass and subsequently annealing were investigated by Rutherford baekscattering and optical absorption techniques, optical absorption spectra showed that the implanted Ag+ coalesce into colloidal particles, the plasma resonance maximum is at 400 nm. The Ag colloid of 18 A in radius was estimated from measurements of the half-width of the plasma resonance by using the Mie theory and Doyle method.
